The invention relates to a novel security feature in the form of a luminescent marking for integration in a recording material. The security feature comprises a radiation layer (21) with luminescent components and a masking layer (2) with cavity pigments at least partly masking the radiation layer. The pigments in the masking layer (2) are fused by locally defined heal treatment into the form of a marking. The invention particularly relates to a heat-sensitive recording material comprising, in a preferred embodiment, at least one substrate (10), a heat-sensitive recording layer (30), an intermediate layer (21), between the substrate and the heat-sensitive recording layer in the form of a radiation layer with luminescent components and a masking layer with cavity pigments (2), the pigments of the masking layer (2) being fused in the form of a marking by locally defined fusion.

The object of the present invention is to provide a screening method of a new integrase inhibitor being able to inhibit an HIV infection before the reverse transcription step and having a pharmaceutical site of action totally different from those of traditional integrase inhibitors, a new integrase inhibitor being obtainable by the screening method, and pharmaceutical constituents containing the integrase inhibitor and DNA encoding the integrase inhibitor being greatly expected as new remedies for AIDS. A peptide which specifically binds to a peptide at N-terminal domain of retroviral integrase was screened by phage display method, and as a result of the screening, a peptide being able to inhibit the infection and the proliferation of retroviruses such as HIV-1 before the reverse transcription reaction is obtained.
摘要:
Light-weight oil having a high octane number is produced from waste plastics containing phthalic polyester and/or polyvinyl chloride at a high yield without producing a phthalic sublimate or a carbonaceous residue by pyrolyzing the waste plastics in an atmosphere of steam or a steam/inert gas mixture. The resulting pyrolyzed oil and pyrolyzed gas may be catalytically cracked in an atmosphere of steam or a steam/inert gas mixture. Dechlorination may be performed before pyrolysis is carried out. Pyrolysis is preferably carried out in the presence of at least one of iron hydroxide, hydrous iron oxide and iron oxide.

A synthetic film including a porous; the alumina substrate containing more than 90 wt % of alumina pores in the alumina substrate have a mean diameter of 0.1.about.3.0 .mu.m. A zeolite crystal body is formed in the pores and on the substrate. The synthetic film is manufactured by preparing the alumina substrate, immersing the substrate in a slurry containing zeolite crystal and its precursor prepared from a silica source using sodium silicate or water glass, and subjecting the substrate with slurry to a hydrothermal crystallization at least one.
